Thanks for your questions. If you have prescriptions from medications, you can add them together and the same goes for the prescriptions from the dentist as well. Another suggestion is to go to your pharmacy and ask them to give you a printout for the tax year. Then you can enter the total amount. Thanks again.
NOTE: If you file electronically, keep all the supporting documents in case the CRA asks to see them.
